Front portions of a rotatable operating knob for latches and locks



FIG. 1 is a perspective view showing front, left and bottom features of a first embodiment of our design;

FIG. 2 is a perspective view showing front, right and top features thereof;

FIG. 3 is a front elevational view thereof;

FIG. 4 is a top plan view thereof;

FIG. 5 is a left side elevational view thereof;

FIG. 6 is a right side elevational view thereof;

FIG. 7 is a bottom plan view thereof;

FIG. 8 is a perspective view showing front, left and top features of a second embodiment of our design; and,

FIG. 9 is a front elevational view thereof.

Top, right, left and bottom views of the second embodiment are not shown inasmuch as they are identical to and would merely repeat what is already depicted in the top, right, left and bottom views of FIGS. 4, 5, 6 and 7, respectively. 

We claim the ornamental design for front portions of a rotatable operating knob for latches and locks, as shown and described.
